408 NATURE-STUDY REVIEW [16:9— Dec, 1920 



The Cornell Rural School Leaflet for November, written by Dr. 

 E. Laurence Palmer, deals with aquatic insects and completes in a 

 most interesting manner the work suggested in the March leaflet on 

 the fishes and plants of the streams and ponds. The insects and 

 other creatures living in still waters are dealt with separately from 

 those living in moving waters. These little water dwellers are 

 figured in outline so that each may be readily recognized by the 

 child as he finds it in the water, each figure is numbered and on the 

 very practical and interesting life history chart following the pic- 

 tures these numbers refer to the name and habits as far as known of 

 each species. In addition are notes on fifty things to be seen in 

 November in the fields and woods with suggestions as to where they 

 may be found.
